Thread: Trouble w/ EZ-wiring Harness and SBC

Tweet

Here is what you should have it hooked up like:

1) The wire labeled "starter" is ok going to the ST on the switch. You are ok there. The other end of that wire should go to the skinny post on the Chevy solenoid that is to the right of the fat post, where you connected your positive battery lead. Since it is cranking, it looks like you have done this correctly.

2) Where you goofed up is that you connected the one that said "coil power" to the switch, along with the other one that says "power to ignition", on the same terminal. Leave the "power to ignition" alone, and move the "coil power" to the same + terminal on the coil where you hooked up the one from the starter solenoid.

You may have to run this one through a resistor (see what the instructions say, or it may already be a resistor type wire.

What is happening is, you are getting 12 volts from the solenoid to fire the coil while cranking, but when you are releasing the key to the run position, no power is going to the coil to keep it going.

I think you are one wire away from having it be ok.

Great. I hope that's it. In the past I just followed a diagram and went with it.... I can't tell how this harness was assembled.... and 21 cicuits definitely is intimidating. I'll be trying this bright and early tomorrow. I'll let you know how it goes. Thanks.

got it working, but did it a different way. I kept having 30A fuses blow, so I disconnected the wire from the starter to the coil, put in a 40A fuse, a resistor in the power wire to the cable and everything seems to be hunky doory.


we'll see. I have been taxing Mallory's tech support group because I have a uni-lite module that fails their trigger test, yet the car still runs. Both parties are baffled.
